While configuring HADR with SSL between Primary DB and Standby DB, standby DB failed to be started
with the following error:
ADM12510E Unable to establish HADR primary-standby connection with
host: "192.168.22.20". Reason code: "13"
The error code indicates the following :
13
The HADR_SSL_LABEL configuration parameter is not valid or has
expired on the primary database or the standby database.
The following message can be found in db2diag.log:

To resolve the problem, firstly verify HADR_SSL_label is correctly configured in your database configure parameters.
You can verify the certificate used in HADR_SSL_label has been added to your key db on Primary and Standby:
gsk8capicmd_64 -cert -list -db <full path to your key db> -stashed
Another thing to investigate is whether database configure parameter HADR_TARGET_LIST on Primary has included the standby database to be established
and vice versa.
